ms-access-2007

问题 I have very little experience with Access Databases however I have wrote a similar VBA macro in excel. I am trying to copy rows from one .mdb file into the exact same table on a different .mdb file. However I would like it to only import it if it does not already exsist. Could someone please advise me the best way to go about this and maybe some code I can use and modify? I have already looked around stack overflow and can't seem to find any examples that work. There are 8 different tables

问题 Could you recommend a good resource on learning MS Access from the perspective of a developer with a good background in SQL Server. Also some best practice tips would be welcome, in areas such as multi-user access support security; both the database and the front end Access interface (Forms,Reports) deployment Basically if you have experience in both SQL Server and MS Access development what best practice advice would you give to your fellow developer with SQL Server experience that needs to

问题 I'm really struggling to 'Transform' or pivot this simple two column table, is there a way ? All the solutions I have found so far ( pivot / transform / crosstab etc) require the data to have some kind of third field index number in order to create the column names. In my case each Itemcode can have any number of Itemimage and those itemimage sometimes are valid for more than one Itemcode . Typically the number of itemimage will be less than 20 but there are tens of thousands of Itemcode .

问题 I have written an ms-access function in a module called ‘StripLead’. I made a single line procedure called ‘CallFunction’. Now when I call this procedure from ms-access it works fine. But when I call this procedure from C# I get error: Undefined function 'Striplead' in expression. Ms-access module code: Public Function StripLead(pstrPhrase As String) As String Dim strFirstWord As String Dim strReturn As String Dim intPos As Integer strReturn = pstrPhrase intPos = InStr(pstrPhrase, " ") If

问题 Using C, I am trying to create an Access 2007 database file using ODBC by way of the SQLConfigDataSource function. char szDriverName[] = "Microsoft Access Driver (*.mdb, *.accdb)"; char szAttr[] = "CREATE_DB=c:\access2007.accdb"; SQLConfigDataSource(NULL, ODBC_ADD_DSN, szDriverName, szAttr); I want the file extension of the new database to be .accdb but when I run the code above, I always get c:\access2007.accdb.mdb. I can specify 12.x (accdb) or 4.x (mdb) from ODBC Admin as in the image

问题 Where I work we receive electronic meters from customers and try to solve the errors they have. We will receive 4-8 meters at a time that all have the same problem, same specs, same everything, the only thing different between each meter is the Serial Number. I want to be able to enter every serial number, and the common specs all in one form to create multiple records. Here's a pic of what I have for the form. I was able to create records for just one serial number at a time, but I would

问题 I am trying to hide specific columns in an Access 2007 split form through code. I need the form to check certain conditions to see whether it needs to display a column or not. I have code in the form's 'Activate' event to hide the column like this: txtControl.ColumnHidden = True This code works in the "Open" event, but if I hide the column on Activate, it won't display these changes until I close the form and open it again. I have tried calling the form's refresh, repaint, and requery methods

问题 I've implemented an auditing trigger on one of my tables, it basically copies the old record and the new record into a table called ..._Audit, along with date and user. I'll post my script further down. The problem is that, when I insert a new record in Access then tab across, it refreshes and shows the first record in the table. An example of this is below - I have added the first three records then refreshed, then I added three more of the exact same data After adding them I should be

问题 If you've read my other recent questions, you've prob'ly picked up that I'm not really an Access developer.... Most of my background is in VB, where I assiduously avoided bound controls. Now I'm working in Access 2007. I have form that's based on a table (well, a single-table query), and a subform upon it based on a one-to-many child table. I want to detect user-made changes in the data on either of these forms so that I can update a date stamp in the parent table. The actual date field is
